Impedance pneumography has a significant advantage for continuous and noninvasive monitoring of respiration, compared with conventional flowmeter-based ventilation measurement technologies. While thoracic impedance is sensitive to pulmonary ventilation, it is also sensitive to physiological activities such as blood flow and cardiomotility, in addition, body movement/posture. This paper explores the possibility of simultaneously monitoring pulmonary ventilation, blood circulation and cardiomotility by bioimpedance measurement. Respiratory, blood perfusion and cardiomotility signals are extracted using the wavelet method from thoracic impedance data measured in breath-holding and tidal breathing statuses, to investigate signal strength and their dependency. This research provides a foundation for the development of bedside devices to monitor various physiological activities.
